Application filed January 26, 1920.

To all 107mm z' may concern Be it known that I, CYPRIEN EDOUARD PAUL JULIEN, a citizen of the French Re public, and residing in Paris, France, Al1 Boulevard Haussmann, have invented certain new and useful Improvements in and Relating to Vehicle-VVheels, of which the following is a complete specification.

This invention has for its object to provide an additional wheel rim applicable to all kinds of vehicle wheels but intended more particularly for tractors, agricultural machines, and any automobile vehicles re-- quired to travel over various kinds of ground, such as hard roads and soft ground as in fields and the like.

The applicant has before proposed to con.- struot a wheel having a plain tread provided Von its internal surface with lateral rshaped projections, which come into operation when the said tread sinks beyond its own thickness into soft ground.

rThe present invention consists in providing any desired number of these lateral V- shaped projections on a ring of suitable diameter, less than the external diameter of the tire of the vehicle wheel, said ring being preferably in one with said projections andbeing adapted to be applied lateri ally against any wheel and fixed thereto by suitable means in such a manner that the tire of the wheel whether metal or resilient eter of the tread and giving to the wheel.

supports independent of the tire.

ln the accompanying drawing which shows, by way of example, one constructional form of the invention,

Figure l is an elevation of a wheel provided with an additional rim in accordance "a with this invention.

Fig. 2 is a partial vertical section of llig. 3 is a' perspective view of a wheel with a tire and illustrating the mounting of an additional rim.

rThe invention comprises a ring a of a Specification of Letters Patent,

fatented o serial no. 354,239.

form suited to the vehicle wh oon which it is desired to fix it, said ring being less in diameter than the tire c on which the wheel ordinarily travels.

This ring a is provided with any desired number of if-shaped projections (Z, preferably in one therewith, the legs of which are turned toward the center of the wheel. The ring a is also provided with holes for the passage of bolts e or other means serving to fix said ring to the wheel 79.

rlhe function of this additional rim is that as soon as the vehicle gets on to soft ground into which the ordinary wheel has a tendency to sink the said projections come into operation, dig themselves into the ground, and act energetically in proportion to the amount the wheel sinks in to oyercome the resistance to traveling.

The if-shaped projections may be provided with additional removable parts, for example, in the form of blades or teeth or spikes g .(see Fig. l) projecting beyond the tread and capable of biting into a ren sisting track such as frozen ground.

Between adjacent t-.shaped projections there may also be' mounted, without screw or bolts, intermediary elements of suitableform which effect an increase in the diameter of the tread and may, for ample, be constituted as shown at .7L (see ed `V-shaped lateral projections, and bow- 1"" shaped filling' elements frictionally held between a pair of said lateral projections.

2. An auxiliary wheel rim comprising a ring adapted to be detachably secured to one side of the wheel, the greatest diameter of said rim being less than the enternal diameter of the tire of the wheel, integral inwardly extending annular `flange project-ing from the lower end of said auxiliary rim and abutting the web of the wheel, and inverted if -shaped projections extending laterally from said rim, and means for detachably securing said rim to one side of the wheel.

3. An auxiliary wheel rim comprisingl a ring of less diameter of the tire and provided with inverter- X"- (fil shaped lateral projections, and bow shaped filling elements frictionally held between a pair of said lateral projections, the arc of said elements lying flush With the circumference of the aforesaid tire tread.

4. In a Vehicle Wheel, a removable auxiliary rim secured to one side of the Wheelsaid rim providedl With spaced apart inverted V-shaped lateral projections, and filling elements adapted to be inserted bef tween adjacent pairs of projections said elements included an arcuate tread member;

and resilient side arms, said arms provided with gripping means at their free ends and frictionally engaging the free ends of the 15 side arms of the said inverted V-shaped lateral projections.

In testimony whereof I have hereunto set my hand at Paris (France) this 29th day of December, 1919.
